=== The Location of Personal Sampler Filter Heads === B. B. Chatterjee M.B, M. K. Williams D.M, Joan Walford A.I.S & E. King B.Sc (1968) The Location of Personal Sampler Filter Heads, American Industrial Hygiene Association Journal, 30:6, 643-645, DOI: 10.1080/00028896909343188 [https://www.tandfonline.com/doi/abs/10.1080/00028896909343188] Abstract Fifteen pasters in an electric accumulator factory each wore two personal samplers simultaneously for two consecutive shifts. The filter heads were attached to the upper left chest, one about 5 inches below the other. During the second shift the locations of the two heads were interchanged. The mean concentration obtained with the filter heads in the upper position was 0.181 mg/m3, while that obtained in the lower position was 0.225 mg/m3. The difference was 22% of the overall mean, and statistically highly significant (p < 0.01). Differences between the six samplers used were not significant. It was concluded that the location of the filter head should be defined more precisely than has been suggested for other jobs, and that the findings will be of particular importance when deriving threshold limit values. Own Comments: * Trying to find the whole article * 1968!
